What is Learning?• Learning is a change in knowledge,
understanding, attitude, behaviour and performance as a result of instruction

Three types of learning
Cognitive
Affective
Psychomotor

Cognitive learning levels (Bloom)
• Evaluation• Synthesis• Analysis• Application• Comprehension• Recall of factual information
Copyright@Titi Savitri
Psychomotor learning levels• Adapting and originating
(modifies performance as conditions change)
• Complex overt response (behaviour is skilled,smooth, efficient, with minimum time and effort)
• Mechanism (learned behaviour is habitual)
• Guided response (under instructor guidance)
• Set (preparatory adjustment for particular action)
• Perception (awareness of objects and qualities)

Verbal information- memory or recall
Cognitive strategies- learning how to learn and think
Motor skills- goal directed muscular movement
Attitudes- mental state influencing action

Definition of Skills• An organized and co-ordianted pattern
of mental and/or physical activity in relation to an object or other display information, usually involving both receptor and effector processes. It is build up gradually in the course of repeated training or other experience (Patrick, 1992)

Characteristics of Skills• Skills are learned or trained• Skills implies some coordinated
physical or cognitive activity to achieve a goal
• Skills implies flexible or adaptive performance
Copyright@Titi Savitri
Theories of Skills Acquisition• The cognitive phase – intellectualisation
process in learning new tasks• The fixation of association phase – correct
patterns of behaviour are slowly established by practice with errors being gradually eliminated
• The autonomous skill – skills become more automatic and requires fewer pyschological resources (Fitts, 1992)
Copyright@Titi Savitri
Theories of Skills Acquisition• Learning skills proceeds through two
stages: – the verbal motor – cognitive and
associative phases (important instruction and feedback)
– the motor – established(Adam, 1987)
Copyright@Titi Savitri
Theories of Skills Acquisition• A schema theory of motor learning
(Schmidt, 1975):– The initial conditions– Response specifications– Sensory consequences– Response outcome

Davis and Harden (1999)
• an active learning stimulated by, and focused round a clinical, community or scientific problem
Copyright@Titi Savitri
Ross (1991)• Students work on the problem which is
explicitly used to get students themselves to identify and search for the knowledge, that they need to obtain in order to approach the problem
Copyright@Titi Savitri
Albanese and Mitchel (1993)
• instructional method characterized by the use of patient problems as a context for students to learn problem-solving skills and acquire knowledge about the basic and clinical sciences
Copyright@Titi Savitri
Dolmans (1994)
• Faculty objectives are translated into a problem, usually consisting of a set of phenomena in need of some kind of explanation. Students analyse these problems, attempting to understand the underlying principles or processes through small-group discussion. During discussion, questions which remain unanswered are identified. These questions or learning issues serve as a guide for independent and self-directed learning.

• The problem acts as a stimulus for learning• An educational approach• A student-centred approach• Active processing of information• Activation of prior knowledge• Meaningful context• Opportunities for elaboration/organization of• Collaborative

• Further indiction of the importance of organization is obvious from the finding of active rearrangement of randomly presented lists. Even though items from various categories are presented in random order, subjects group the items into their appropriate categories at recollection.

Prior Knowledge
• Determinant of nature and amount of new information to be processed
• Need to be activated by contextual cues

Organization of Knowledge
Copyright@Titi Savitri
Knowledge Structure• The way knowledge is structured in
memory makes it more or less accessible for use

Learning occurs within a contextsimilar to the one in which it will be applied.
Copyright@Titi Savitri
Contextual Cues• The ability to activate knowledge in the
LTM and to make it available for use depends on contextual cues
Copyright@Titi Savitri
Motivation• To be motivated to learn,
prolongs the amount of study time

Definition• A process in which individuals take
initiative with or without the help of others in diagnosing learning goals, formulating learning objectives, searching learning resources, selecting and implementing learning experiences and evaluating learning outcomes
(Knowles, 1975)
Copyright@Titi Savitri
• A learning process, primarily motivated by students’ own aim (intrinsic motivation)
• Freedom to self-pace• Freedom to follow alternative learning
pathways• Freedom to select learning goals• Freedom to access
Copyright@Titi Savitri
• Programme of studies determined by the individual student and pursued under the guidance of a personal tutor
• Student controlled, structured content and process, developed internally by the students
Copyright@Titi Savitri
• A programme of learning organised so that students are able to proceed through a programme at their own pace, filling in the gaps that they do not know and omitting what they do know.

Characteristics of Small Group Learning
• Active Participation• A Specific Task• Reflection
Copyright@Titi Savitri
Benefits of SGL• Active Learning• Self-motivation• Promotes deep learning• Application of ideas• Adult learning• Develop transferable skills
Copyright@Titi Savitri
During SGL• Adequate introduction • Ensure students understand what to do• Facilitate learning• Group dynamics: forming, storming,
norming, performing• Debriefing
Copyright@Titi Savitri
Copyright@Titi Savitri
Concerns• High cost of laboratory work• Severe time constraints• Conventional laboratory work is
ineffective to foster understanding and application of scientific concepts to solving problems
Copyright@Titi Savitri
Aims of Laboratory Work• Teaching relevant technical skills • Understanding scientific principles• Understanding process of scientific
enquiry• Developing systematic problem-solving
skills• Nurturing the development of
professional attitudes, practices and commitment
Copyright@Titi Savitri
Purpose of Laboratory Work (1)
• Teach theoretical material not presented elsewhere
• Illustrate and amplify lecture material• Develop manipulative skills• Develop ability to follow instructions• Familiarize students with instruments
and apparatus
Copyright@Titi Savitri
Purpose of Laboratory Work (2)
• Develop observation skills• Develop skills in gathering and
interpreting data• Develop a concern for accuracy and
precision• Develop skill in communicating
experimental results• Develop the ability to write coherent
and well-argued reports
Copyright@Titi Savitri
Purpose of Laboratory Work (3)
• Develop the capacity for self-directed learning
• Encourage independent thinking• Stimulate thought through
experimental interpretation• Develop students’ skill in problem
solving with a wide number of variables and many possible solutions
Copyright@Titi Savitri
Purpose of Laboratory Work (4)
• Encourage enterprise, initiative and resourcefulness
• Develop personal responsibility and reliability of experimentation
Copyright@Titi Savitri
Researches on Laboratory Work
• Less effective for teaching factual knowledge, concepts and scientific enquiry or problem solving skills
• Emphasize on low grade skills• Foster superficial mechanistic
knoweldge• Little understanding between theory
and practice
Copyright@Titi Savitri
Drawbacks of Conventional Laboratory Work
• Ritual: students follow instructions and not required to think
• Assessment: asking factual knowledge• Teacher-centred• Lack of prior knowledge• Design of curriculum: knowledge in
unconnected
Copyright@Titi Savitri
Innovative Laboratory Work• Experiential-based learning• Student-centred• Opportunities for reflection,
commitment and active exploration

Demonstrations• Illustrate and consolidate theoretical
principles• Should be held shortly after the lecture
Copyright@Titi Savitri
Exercises• Tightly structured experiments• Students follow precise instructions• Learn observational and manipulative
skills, as well as confirm theory
Copyright@Titi Savitri
Structured Enquiries• Partially structured experiments which
require students to develop their own procedures and interpretation of results
• To learn observational, manual, interpretative and problem-solving skills
Copyright@Titi Savitri
Open Ended Enquiries• Identify a problem• Formulate a solution• Develop experimental procedures• Interpret result• Recognize implications
– To learn advanced problem-solving skills– To learn resarch skills– To learn applicatin, analysis, synthesis and
evaluation (higher order thinking skills)
Copyright@Titi Savitri
Projects• Explore a field deeply• Increase intellectual curiousity• Develop innovativeness to the full
